CLC5509 - Ultra-Low Noise Preamplifier

Description

The CLC5509 is a high performance, ultra-low noise preamplifier designed for applications requiring unconditional stability for wide ranges of complex input loads.

Both input impedance and gain are externally adjustable, which make it simple to interface to peizoelectric ultrasound transducers.

Features

  • n n n n n n n n 0.58nV total input noise @ 12MHz < .5ns group delay repeatability High cutoff.
  • 3dB @ 33MHz Low cutoff.
  • 3dB @ 0.5MHz 2.0dB noise figure @ 50Ω.
  • 60dBc intermod for 2VPP @ 5MHz Supply current: 11mA Available in 8-pin SOIC.

CLC5509 Ultra-Low Noise Preamplifier January 2000 CLC5509 Ultra-Low Noise Preamplifier General Description The CLC5509 is a high performance, ultra-low noise preamplifier designed for applications requiring unconditional stability for wide ranges of complex input loads. Both input impedance and gain are externally adjustable, which make it simple to interface to peizoelectric ultrasound transducers. The CLC5509 preamplifier’s low 0.58nV total input noise makes it ideal for noise sensitive front ends. The high repeatability in group delay over voltage and temperature translates into precision edge measurements for Doppler applications. The IC consists of an emitter input, common base amplifier stage followed by a low distortion, closed loop buffer.
